This document applies to distributor valves and distributor-isolating devices.
The distributor valves contained in this document are of graduable release type. Direct release types are not included.
Functionally they are regarded as not containing relay valves of any type, even if the relay valves are physically an integral part of the distributor valves.
This document applies to both distributor-isolating devices mounted separate from the distributor valve and distributor-isolating devices integral with the distributor valve.
This document specifies the requirements for the design, testing and quality assurance of distributor valves and distributor-isolating devices.
The distributor valve and distributor-isolating device are intended to be part of a brake system mounted in a vehicle with maximum length of 31 m and maximum brake pipe volume of 25 l taking into consideration brake pipe inner diameters between 25 mm and 32 mm.

b) guided;
c) travelling vertically or along a path within 15 degrees maximum from the vertical;
d) supported by rack and pinion or suspended by steel wire ropes;
e) travelling with a speed not more than 1,0 m/s for permanent installed lifts and not more than 0,4 m/s for temporary installed lifts.
NOTE Annex A identifies the specific requirements applicable to the permanent installed lifts, respectively to the temporary installed lifts.
1.2 This document identifies hazards as listed in Clause 4 that arise during the various phases in the life of such equipment and describes methods for the elimination or reduction of these hazards when used as intended by the manufacturer.
1.3 This document does not specify the additional requirements for:
a) operation in severe conditions (e.g. extreme climates, strong magnetic fields);
b) noise;
c) operation subject to special rules (e.g. potentially explosive atmospheres);
NOTE Directive 2014/34/EU concerning equipment and protective systems intended for use in potentially explosive atmospheres can be applicable to the type of machine or equipment covered by this document. The present standard is not intended to provide means of complying with the essential health and safety requirements of Directive 2014/34/EU.
d) electromagnetic compatibility (emission, immunity);
e) handling of loads the nature of which could lead to dangerous situations;
f) the use of combustion engines;
g) hydraulic drive units;
h) hazards occurring during manufacturing process;
1.4 This document is not applicable to:
a) builders hoists according to EN 12158-1:2000+A1:2010, EN 12158-2:2000+A1:2010 and EN 12159:2012 and transport platform according to EN 16719:2018;
b) elevating control stations according to EN 14502-2:2005+A1:2008;

c) lifts according to EN 81-20:2014 and EN 81-50:2014;
d) work platforms carried on the forks of fork trucks;
e) work platforms;
f) funiculars;
g) lifts specially designed for military purposes;
h) mine lifts;
i) theatre elevators.
1.5 This document deals with the complete lift design but excludes the design of the crane. It includes the base frame and base enclosure of the lift but excludes the design of any concrete, hard core, timber or other foundation arrangement. It includes the design of mast ties and the design of anchorage parts between the mast tie and the crane structure. This document also includes the design of the landing gates and their fixings.
1.6 This document also deals with the information to be exchanged between the manufacturer of the lift and the crane user organization or the manufacturer of the crane.

This document specifies safety requirements and their verification, environmental requirements and related test methods, and minimum performance limits, for the design and construction of knapsack combustion engine-driven airblast sprayers as defined in 3.9.
It describes methods for the elimination or reduction of hazards arising from their use. In addition, it specifies the type of information on safe working practices to be provided by the manufacturer.
It addresses general operating parameters as well as the potential deposition of spray droplets under specified controlled conditions.
This document deals with all significant hazards, hazardous situations and events, excepting those arising from vibration transmitted to the back of the operator.
It is applicable to knapsack combustion engine-driven airblast sprayers when they are used as intended and under the conditions foreseeable by the manufacturer (see Table A.1).
It is not applicable to:
— hydraulic pressure sprayers;
— thermal sprayers;

This document specifies the functionality, position, constraints and control of a magnetic track brake system (MTB system) installed in bogies for use in emergency braking and in low adhesion conditions on Mainline Trains with speeds up to 280 km/h. It covers high suspension types of MTB only and not high/low and low suspension type of MTB.
This document also contains test methods and acceptance criteria for an MTB system. It identifies interfaces with electrical equipment, bogie, track and other brake systems.
On the basis of the existing international and national standards, additional requirements are defined for:
— conditions of application for the MTB system;
— retardation and brake forces;
— functional and design features;
— strength requirements;
— type, series and vehicle implementation tests.
For design and calculation a “reference surface” is established.
